In the first part of this chapter, I summarise some of the issues in the philosophy of mind which are addressed in Kant’s Critical writings. In the second part, I chart some of the ways in which that discussion influenced twentieth-century analytic philosophy of mind and identify some of the themes which characterise Kantian approaches in the philosophy of mind.

This paper explores Kant’s account of propositional content and its implications for the relationship between his notions of knowledge (Wissen) and cognition (Erkenntnis). While previous commentators commonly read Kant as holding a Fregean theory of propositional content, in this paper I argue that Kant’s theory of propositional content aligns more closely with Peter Hanks’ recent account. According to my reading, Kant holds that individual acts of judging are both ontologically and explanatorily prior to propositions or Kantian judgments (Urteil). Furthermore, on (...) my reading, acts of judging for Kant are acts of assertively predicating a property of an object rather than merely acts of neutral predication. This reading challenges the lately popular view that Kant’s notions of knowledge and cognition are not only distinct but also disjunct. I instead suggest that we should regard Kantian knowledge that requires cognitions as its grounds as a species of Kantian cognitions. (shrink)

According to recent commentators like Paul Guyer, Kant agrees with Hume's Dialogues Concerning Natural Religion that physico-theology can never provide knowledge of God and that the concept of God, nevertheless, provides a useful heuristic principle for scientific enquiry. This paper argues that Kant, far from agreeing with Hume, criticizes Hume's Dialogues for failing to prove that physico-theology can never yield knowledge of God and that Kant correctly views Hume's Dialogues as a threat to, rather than an anticipation of, his own (...) view that the concept of God provides a useful heuristic principle for science. The paper concludes that Kant's critique of physico-theology reflects Kant's deep dissatisfaction with Hume's manner of argumentation and suggests that Kant's attempt to provide a more successful critique of physico-theology merits continued philosophical attention.

Even though Kant’s theory of cognition (Erkenntnis) is central to his Critique of Pure Reason, it has rarely been asked what exactly Kant means by the term “cognition”. Against the widespread assumption that cognition (in the most relevant sense of that term) can be identified with knowledge or if not, that knowledge is at least a species of cognition, we argue that the concepts of cognition and knowledge in Kant are not only distinct, but even disjunct. To show this, we (...) first (I) investigate Kant’s explicit characterizations of the nature of cognition. As it turns out, he introduces several different notions that must be carefully distinguished before identifying the one that is central to his project in the first Critique. We then (II) consider the basic features of Kant’s conception of knowledge, indicating both how it involves assent and objective justification and how it relates to our contemporary conception. Next (III), we compare and contrast Kant’s understanding of cognition and his conception of knowledge in a way that allows us to present their fundamental differences and connections. We argue that while cognition, in the most relevant sense, is a species of representation that differs from other representations in that it involves the conceptual determination of a sensibly given object, knowledge (for Kant) is a kind of assent to a judgment that requires consciousness of a sufficient epistemic ground. Finally (IV), by appreciating the differences between cognition and knowledge, we explain several of the implications this conception of cognition has for some of Kant’s main claims in the Critique of Pure Reason as a whole. Among other things, we show how Kant can deny cognition of specific things in themselves while allowing philosophical knowledge about things in themselves in general (e.g. that they exist, are not in space and time, etc.).

I argue for a new delimitation of what Kant means by ‘cognition [Erkenntnis]’, on the basis of the intermediate, transitional place that Kant gives to cognition in the ‘progression [Stufenleiter]’ of our representations and our consciousness of them. I show how cognition differs from mental acts lying earlier on this progression—such as sensing, intuiting, and perceiving—and also how cognition differs from acts lying later on this progression—such as explaining, having insight, and comprehending. I also argue that cognition should not be (...) confused with ‘knowledge [Wissen]’, insofar as knowledge represents the culmination of a separate orthogonal progression of acts of ‘holding-true’. Along the way, I show how having in focus the specific progression from representation, to consciousness, to cognition allows us to better appreciate the architectonic significance of the progression of Kant’s analysis in the first Critique, and also helps to illuminate the unity of Kant’s account of cognition itself across its variety of forms.

The problem of Kant’s Neglected Alternative is that while his Aesthetic provides an argument that space and time are empirically real – in applying to all appearances – its argument seems to fall short of the conclusion that space and time are transcendentally ideal, in not applying to any things in themselves. By considering an overlooked passage in which Kant explains why his Transcendental Deduction is ‘unavoidably necessary’, I argue that it is not solely in his Aesthetic but more so (...) in his Deduction where he intends to provide his argument for the transcendental ideality of space and time. His Deduction shows that space and time do not have a valid application to any things in themselves by arguing that the categories do have a valid application to everything in space and time, but that the categories do not have a valid application to any things in themselves.

The problem of Kant's first Critique is the problem of pure reason: how are synthetic judgments possible a priori? Many of his readers have believed that the problem depends upon a delimitation within the class of a priori truths of a class of irreducibly synthetic truths—a delimitation whose possibility is doubtful—because absent this it is not excluded that all a priori truths are analytic. I argue, on the contrary, that the problem depends on nothing more than the human knower's everyday (...) consciousness of her own finitude: her dependence in thinking and knowing on what is given to her. The problem is a difficulty about how the concepts which figure in metaphysical judgments could represent reality given that they cannot do so in the way in which concepts figuring in empirical judgments do. Empirical judgment here functions as exemplary of thought and knowledge because it is exemplary of finite thought and knowledge. Mere analysis could not, therefore, dissolve the problem even in principle, because to say that a concept can be analyzed is not yet to explain the possibility of its real representative power. The significance of the analytic-synthetic distinction in the context of the problem of pure reason is that its formulation allows Kant to say this. (shrink)

Kant holds that the applicability of the moral ‘ought’ depends on a kind of agent-causal freedom that is incompatible with the deterministic structure of phenomenal nature. I argue that Kant understands this determinism to threaten not just morality but the very possibility of our status as rational beings. Rational beings exemplify “cognitive control” in all of their actions, including not just rational willing and the formation of doxastic attitudes, but also more basic cognitive acts such as judging, conceptualizing, and synthesizing.

I examine a range of issues concerning Kant's conception of cognitive spontaneity. I consider whether we can cognize or know ourselves as spontaneous cognizers, and why Kant seems to regard the notion of cognitive spontaneity as less problematic than the idea of moral spontaneity. As an organizing theme of my discussion, I use an apparent tension between the A-edition and the B-edition of the first Critique. Against common interpretations, I argue that in the B-edition Kant does not revoke his claim (...) that we can cognize, and even know, that our noumenal selves are absolutely spontaneous cognitive agents.

In Kant’s idealism, all spatiotemporal objects depend on the human mind in a certain way. A central issue here is whether the existence of spatiotemporal things requires that these things are, at least at some point, objects of some actual experience or of a merely possible experience. In this essay, I argue (on textual and philosophical grounds) for the latter view: spatiotemporal things exist (or spatiotemporal events occur) if they are objects of a (suitably qualified) possible experience.

It is commonly claimed that Kant's critical philosophy aims to limit reason's speculative use and its metaphysical pretensions. This paper argues that such claims should be amended in light of a technical distinction between negative limits and positive boundaries that Kant held throughout his career. Kant's only extended discussion of this distinction appears in §§57–60 of the Prolegomena, a division entitled “On pure reason's boundary‐determination”. I examine these sections in detail in order to elucidate the account of the limits and (...) boundaries of the activity of different cognitive faculties in the Critique of Pure Reason. I argue that once we understand a key ambition of the Critique to be the positive determination of the boundary between objects of experience and things in themselves, we gain insight into the essential contribution that Kant's theory of the positive utility of ideas of reason makes to the critical philosophy.

Kant’s published arguments for the non-spatiotemporality of things in themselves have not been well received. I argue that Kant has available to himself an argument for the non-spatiotemporality of things in themselves that is premised upon a disparity between the compositional structure of the intelligible world and the structure of space and time. I argue that Kant was unwaveringly committed to the premises of this argument throughout his career and that he was aware of their idealistic implications. I also argue (...) that this argument is consistent with Kant’s restrictive mature epistemology. If my argument is successful, then even if Kant’s published arguments for transcendental idealism fail, we need not regard his ambitious metaphysical project as a failure. (shrink)

In the Transcendental Dialectic of the first Critique, Kant famously claims that even if ideas and principles of reason cannot count as cognitions of objects, they can play a positive role when they are used “regulatively” with the aim of organizing our empirical cognitions. One issue is to understand what assuming “regulatively” means. What kind of attitude does this “assuming” imply? Another issue is to characterize the status of ideas and principles themselves. It is to this second issue that this (...) article is dedicated. Some interpreters have suggested that ideas and principles that can be assumed regulatively consist of propositions that we know are false. Others have suggested that at least some regulative ideas, as for example the idea of the homogeneity of nature, consist of propositions that we know are true but are indeterminate. Still others argue that, in assuming regulative ideas and principles, we assume propositions that cannot be proved true, but are nonetheless possibly true. In this article, I reject the view that regulative ideas consist of true but indeterminate propositions. Moreover, I argue that it is wrong to presuppose that only one of the remaining two options can apply to Kant’s account of regulative ideas and principles. By contrast, I submit that while in some cases assuming regulative ideas and principles does involve assuming some propositions that we know are false, this is not true for all regulative ideas and principles. More specifically, assuming regulative ideas involves assuming false propositions when assuming them means assuming that a “totality of appearances” is given. (shrink)

This paper develops its exegetical claim by building mainly on a reconstruction of a central argument in the Critique of Pure Reason and supporting it with material from Kant’s other critical works. It argues that Kant’s philosophy does not permit us any judgment about things in themselves whatsoever. This could be called a form of ignorance, albeit a unique one. On the developed reading, Kant claims that there cannot be any objectively valid judgment about things in themselves, and since so-called (...) judgments without objective validity are actually no judgments at all, there is no judgment about things in themselves available to us – not even a negative one. The paper considers the theses and antitheses of the antinomies, analytic judgments, and the practical postulates as potential candidates for such judgments, each of which fail the objectivity test. It ends by concluding that we should read Kant’s critical writings in such a way that they do not feature any judgments about things in themselves and suggests one way to do so: putative judgments of this sort could be read as higher-order judgments about the concept of a thing in itself.

Los noumena son, en principio, conceptos límites. En el corpus kantiano encontramos múltiples de ellos, cuyo papel es decisivo en el tratamiento de la metafísica anterior, así como en la propuesta de metafísicas alternativas. Kant, sin embargo, no se detiene a explicarnos de dónde surgen esos conceptos y dónde irían. La presente investigación sugiere que a partir del concepto de nota (Merkmal) presentada en la KrV y desarrollada en la Jäsche Logik, podemos comprender estos noumena como las notas analíticas, suficientes, (...) esenciales y primitivas de las ideas de la razón, tanto teóricas como prácticas.
